Large asteroid simulation This can be used as the basis for building a space station in the future

Astrophysical team from the University of Vienna in Austria Analyze the possibility of building a new space station. Designed to be embedded below the surface of the asteroid To avoid dangerous radiation from the universe And digging for mining, rare minerals easy

A group of scientists published the results of the abovementioned analysis in the academic archive online, arXiv.org, which states that the project is very similar to science fiction. If research has discovered asteroids near Earth, which have large enough geological features

Choosing the body of asteroid as a location of the space station has many advantages. For example, the asteroid rotation causes sufficient gravity to retain the structure and equipment of the space station, without escaping it.

The rocky structure of the asteroid also helps to prevent various hazards from space, such as cosmic rays that are harmful to life. It is also a collection of rare earth elements that people can dig out to make them more useful.

This option is tested with the asteroid model on the computer. It is assumed to have a width of 390 meters and 500 meters long

The research team found this by the centrifugal force generated by the rotation of the asteroid model. Enough enough that the space station and its equipment are so heavy that it can be firmly located in a cave that is dug below the surface. At present there are many asteroids that are in size and shape similar to the models used for testing.

Dr. Thomas Mendil, one of the researchers, said Before swimming under the surface of the asteroid to build this space station This must have a preliminary study. Its structure is strong enough. Later, there is no danger of breaking into small pieces

"There is a possibility that the space station will be shaped cylindrically." By using metallic building materials like aluminum. But if you find an asteroid with a really strong rock layer, it can be used as a natural wall for a space station. "

"It is expected that people will be able to carry out mining activities to find minerals on asteroids over the next 20 years. As for the space station below the surface of the asteroid, this can be true for decades," said Dr. Mendel.
